Weird problem with Polycom QDX 6000

[Anonymous]

Greetings,

In our company we have Polycom QDX 6000 video conferencing system.From last week we have pretty odd problem: when we try to make call with another partner who uses same device on distant location,we cant see or hear him.Weird thing is that he can see and hear us!?Any sugestion would help if anyone else had the same problem or if anyone knows solution 

Thanks in advance:)

Hello Dacha89,

this sounds like a firewall issue / nat issue.

Double-check the correct ports and nat settings on the firewall and endpoint.
